Fig. 11From: Solar flare effects on D-region ionosphere using VLF measurements during low- and high-solar activity phases of solar cycle 24Electron densities determined by LWPC VLF modeling during the M1.0 solar flare of February 08, 2010 (red dashed line—solar minimum), and of November 27, 2012 (blue dashed line—moderate solar activity), compared with normal unperturbed electron densities (solid black line) for NLK to Suva path. Also shown is comparison of electron density plot of Grubor et al. (2008) results (green dashed line) for an M1.1 flare during a period of moderate solar activityBack to article page
